Population abundance and related parameters need to be assessed
to implement effective wildlife management. These essential parameters
are often very hard to obtain for rare, wide-ranging and elusive
species, particularly those listed as endangered or threatened
(IUCN 2001). In Italy, wolves Canis lupus Linnaeus 1758,
now a fully protected species in Western Europe, recently recolonized
the Western Alps after 70 years through dispersal fromtheApennines
(Fabbri et al. 2007). This wolf population is expanding (Boitani
2003), although accurate estimates of trends of population size
and survival are lacking.
